SPINDLE ADJUSTMENT FOR BUTTON-MAKI NG MACHINES.

SPECIFICATION forming part of Letters Patent No. 707,330, dated August 19, 1902. Application filed April 19, 1902. Serial No. 103,819- (No model.)

To all whom, it may concern:

Be it known that I, JOHN HORMBY, a citizen of the United States, residing at Woonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Spindle Adjustments for Button-Making Machines, of which the following is a specification.

This invention relates to machines for making buttons, and more particularly to machines of the class shown and described in my United States Patent No. 61l,8ll, dated October 4:, 1898, for making buttons from vegetable ivory or analogous materials in which the material is operated upon by tools carried by spindle-heads. In shaping, drilling, and other operations performed by such machines absolute accuracy of operation of the tools in order to produce perfect results requires that the adjustment of the tools and their supports must be made with the greatest nicety, as the least deviation in position of the tools will result in damage to the tools, waste of material, and consequent waste of time, thereby increasing the cost of manufacture. In order to avoid any of these difficulties, it is the object of this invention to provide means for accurately and quickly adj ustingthe spindle-bearings of such machines; and with this object in .view the invention consists in such adjusting mechanism, the construction, arrangement, and combination of the parts of which will be first fully described hereinafter and afterward specifically claimed.

In the accompanying drawings, in which I have illustrated one embodiment of my invention, Figure 1 represents in bottom plan view my adjusting mechanism applied to a spindle-bearing. Fig. 2 represents the same in side elevation. Fig. 3 represents the same in longitudinal vertical section on the plane of line 3 3 of Fig. 1, the upper part of the spindle-bearing being broken away. Fig. 4 represents the same in transverse vertical section on the plane of lines 4; 4 of Figs. 1 and 3, the upper part of the spindle-bearing being broken away. Fig. 5 represents the same in transverse vertical section on the plane of lines 5 5 of Figs. 1, 2, and 3, part of the carriage being also shown.

Like reference characters mark the same parts in all the figures.

Referring to the drawings, A indicates a spindle-bearing which is suitably constructed to receive the tool-spindle, (not shown,) said bearing consisting, preferably, of a block of cast metal, and it is provided in its under face with three slideways or grooves, one in each edge and one intermediate the edges of the bottom, the side edge grooves orslideways being formed with inner walls in vertical planes parallel with the planes of the sides of the bearing and with each other and the top walls in a plane inclined to the horizontal, said top walls being each provided with a smaller groove at its inner edge, with side wall and top wall to correspond with those of the main groove. These edge grooves are adapted to receive two arms B B of the block or shoelB', which arms are of a form to fit said grooves and slide therein, having vertical side faces I), inclined tops I), and longitudinal ribs b" to fit the small grooves and prevent lateral displacement or strain upon the arms. The intermediate groove in the bottom of the spindle-bearing has a'horizontal top wall and vertical side walls parallel with each other and at angles to the central vertical plane and the sides of the bearing. This groove is adapted to receive a bar 0 of a form to fit into and slide in it, having a horizontal top face 0 and parallel inclined side faces 0, and provided with a slot D, longitudinally located immediately below a round bore a through the bear ing A. The bearingA and the bar 0 may be I firmly secured to the carriage K of the machine in any suitable manner, as by a binding-bolt (not shown) having its head seated in a T-slot L in the carriage K and passing through the slot D and opening a. Before securing these parts to the carriage-the bar 0 is longitudinally adjusted to the proper position to give the bearing'A its proper lateral adjustment, when the bar and head are firmly secured, as before mentioned. Y

The bar 0 is provided with integral flanges E and F, projecting into the T-slot L of the carriage in the vertical plane of the slot D for the purpose of strengthening the bar and for afiording depth to two slots E and F, one in each flange and both in line with the slot D. Bolts G and H pass up through said slots and are threaded into the spindle-bearing A to securely clamp these parts together when adjusted and ready to be secured to the carriage.

The vertical adjustment of the hearing A is made by sliding the arms B B of the block B longitudinally. This may be accomplished in many ways, means being here shown consisting of a screw I, threaded into the head and adapted to bear against the inner face of the block B, and thus limit its inward move ment, and a smaller screw J, passing inwardly through the block and into the outer end of screw I to hold the block against the head of screw I. By slightly loosening the screw J both screws may be turned together to move the bar B in either direction, after which the screw J is tightened up to hold the block in its adjusted position.

By means of the described construction the hearing may be adjusted laterally and vertically to an extreme degree of nicety, and thus the difficulties due to the lack of such adjusting means are entirely avoided, perfect Work done, and time, tools, and material saved.

Having thus described my invention, what I claim as new is 1. In a machine of the character described, the combination with the spindle-bearing, of means for laterally adjusting it, said means consisting of a bar guided in the longitudinal plane of the head, and means for sliding said bar in a laterally-inclined groove in the bottom of the bearing.

2. In a machine of the character described, the combination with the spindle-bearing provided with a laterally-inclined groove in its bottom, of a bar fitted to slide in said groove, slots in the bar in the longitudinal plane of the bearing and bolts in said slots threaded into the bearing.

3. In a machine of the character described, the combination with the spindle-bearing provided with grooves at the edges of its bottom face having inclined top walls, of a block having Wedge-shaped arms extending into said grooves, means for moving the block and arms longitudinally with relation to the hearing, and means for preventing lateral displacement of or strain upon the arms.

4. In a machine of the character described, the combination with the spindle-bearingprovided with side grooves in its bottom having inclined top walls and an intermediate groove having laterally-inclined side walls, of wedgeshaped arms in the side grooves, a bar with parallel inclined sides in the intermediate groove, and means for adjusting the arms and bar longitudinally in lines parallel with each other and with the sides of the bearing.

Witness my hand this 17th day of April, 1902, in the presence of two subscribing witnesses.
